Cross talk between signaling pathways in pathogen defense.
نویسندگان
چکیده
Plant defense in response to microbial attack is regulated through a complex network of signaling pathways that involve three signaling molecules: salicylic acid (SA), jasmonic acid (JA) and ethylene. The SA and JA signaling pathways are mutually antagonistic. This regulatory cross talk may have evolved to allow plants to fine-tune the induction of their defenses in response to different plant pathogens.

Regulation of tradeoffs between plant defenses against pathogens with different lifestyles.
Plants activate distinct defense responses depending on the lifestyle of the attacker encountered. In these responses, salicylic acid (SA) and jasmonic acid (JA) play important signaling roles. SA induces defense against biotrophic pathogens that feed and reproduce on live host cells, whereas JA activates defense against necrotrophic pathogens that kill host cells for nutrition and reproduction...
متن کاملThe Jak-Stat Signaling Pathway of Interferons System: Snapshots
Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...
متن کاملWRKY70 modulates the selection of signaling pathways in plant defense.
Cross-talk between signal transduction pathways is a central feature of the tightly regulated plant defense signaling network. The potential synergism or antagonism between defense pathways is determined by recognition of the type of pathogen or pathogen-derived elicitor. Our studies have identified WRKY70 as a node of convergence for integrating salicylic acid (SA)- and jasmonic acid (JA)-medi...
متن کاملETHYLENE RESPONSE FACTOR1 integrates signals from ethylene and jasmonate pathways in plant defense.
Cross-talk between ethylene and jasmonate signaling pathways determines the activation of a set of defense responses against pathogens and herbivores. However, the molecular mechanisms that underlie this cross-talk are poorly understood. Here, we show that ethylene and jasmonate pathways converge in the transcriptional activation of ETHYLENE RESPONSE FACTOR1 (ERF1), which encodes a transcriptio...
متن کاملTrade-offs between pathogen and herbivore resistance.
During the past year genetic and pharmacological experiments have revealed a molecular basis for the cross-talk between signaling pathways mediating pathogen and herbivore resistance. These findings provide considerable insight into the apparently contradictory results reported for trade-offs between pathogen and herbivore resistance.
